I've been coming to this gem for over 20 years! The lady owner is always incredibly welcoming and hospitable. Even with inflation hitting hard lately, you can still feel their sincerity in every dish. The portions are huge, and the sashimi is sliced generously thick! What touched us the most was when we mentioned how much we loved the tea, the owner immediately gave us a bunch of roasted rice (Genmai) so we could brew it ourselves! The interior is always cozy and spotless. It's rare to find a place that maintains this level of quality and warmth for decades. Highly recommended!

Broiled Salmon & Mixed Tempura Bento.

I thought I would update my review from before since it's been a few years and am sad to report that it has gone downhill. I know times may be tough, but yikes! BROILED SALMON & MIXED TEMPURA BENTO BOX: I ordered this to go and it came with a scoop of rice, 4 spicy tuna cut rolls (used to be 6), a small clump of salad, tempura (came without the tempura sauce), miso soup, and the saddest/hardest clump of fried/broiled salmon (came with side of teriyaki sauce). The portion has SIGNIFICANTLY shrunk especially for the salmon. The salmon was basically the size of the sauce dish container...I finished it in 2-3 bites. Due to this, I will sadly not be returning.

Lobster seafood hotpot

I love this place, the woman who works here is so friendly and nice. Me and my family came here for a birthday and they made it really special. The sea urchin bowl is really good and unique. The sushi boat as well. And the lobster seafood hotpot. It is casual but I think because of the staff it is special. Would recommend!

Great quality sushi in a friendly mom and pop restaurant! The restaurant itself is very cozy, limited seating but luckily on a Tuesday evening, there was no wait. Small private parking lot adjacent to the restaurant was convenient! The meal starts with complimentary salad, miso soup, and edamame. These were a nice surprise! We then went on to the fried calamari and baked mussels. Calarami was nice and perfectly crispy with a drizzle of a sweet sauce, it was perfect to share amongst three people. The baked mussels were amazing!! Topped with cheese, a sweet and savory sauce, the mussels were juicy boys and definitely got us excited for our main sushi entrees! We went with the albacore roll, spicy tuna roll, eel sashimi, salmon roe sashimi, dragon roll, and yellow tail sashimi. Initial impressions - great presentation, and came out relatively quick! The sashimi was FRESH, and the perfect amount of rice. I dislike when there's any more than a pinch of rice and Mansun did the portions just right! The salmon roe was a generous portion, and with each bite, they popped heavenly in my mouth. The rolls were meticulously made as well and tasted amazing! For the three of us, I think we did well with the portions and by the end, felt quite satisfied... This is when the waitress offered complimentary ice cream! How could we say no...so we all decided on the green tea ice cream. It wasn't too sweet, and was the story book ending to our meal. They do offer bento box style meals with tempura as lunch and dinner specials as well, so in the future I'd absolutely like to try these out! Overall, highly recommend and will definitely be back. Don't let the unassuming exterior appearance of the plaza dissuade you from giving Mansun a try!

Esther was an amazing server for my friends bday dinner! The food was so good , she was so friendly and funny. Made us feel like family! We had a private room that was great for an intimate bday setting.

This place was amazing. Our server was very quick and sweet. As teens we normally don't expect such great service but everyone in the restaurant had positive energy and was very efficient. Along with this the food was great.

Sea urchin bowl
Phyllis L.

The food is always so good here! The sashimi is fresh and the uni bowl was soo flavorful and yummy. I came with my boyfriend and the sushi chef was sweet and made us the most adorable swan couple out of an apple. The owner is a nice Korean lady who has the nicest smile. Service is 10/10 and the food is also a 10/10! I highly recommend this place especially if you like uni!

Veggie Tempura

I can't believe I've been driving by this place for years without stopping in--what a hidden gem! The food here is absolutely amazing and unbelievably fresh. The fish quality blew me away--so high-grade, so clean-tasting, and not fishy at all. I was genuinely surprised at just how good everything was. I tried the sea urchin bowl, which was insanely fresh and flavorful, and the lunch special teriyaki chicken with tempura--the portions were very generous and satisfying. I also ordered the sushi lunch special, and honestly, the fish quality was mind-blowing. It felt like something you'd expect at a high-end sushi spot, not a casual place you just stumble into. On top of the food, the service was excellent. The owner is so kind and welcoming, and they even give out free ice cream at the end, which was such a nice touch. It really feels good supporting a local small business when the experience is this good. (5/5) -- Fresh, delicious, generous portions, and amazing service. I'll definitely be coming back again and again.

Sea Urchin
M S.

Ordered to-go around 11:40 a.m. on Sunday. Food came out fast and was nicely packed. Few sea urchin spines were mixed into the rice, which was a little disappointing, but everything else was fine. Side dishes were light and tasty. Regular size was $33 (large $44 with tax). I'll probably go for the large next time--it was better on my last visit.

Going going gone.

The food is fresh and large portion. The service staff is friendly and gave us great recommendation. There were five of us and we have our room.

Billy L.

The food are amazing. And the prices are reasonable. Miso soup is amazing. Highly recommend to come to this restaurant if you around the area

Austin L.

My go to spot for sushi in the Diamond Bar area! In my opinion they have the best combination of quality, price, and service. The owner/lady in charge is super nice and provides great recommendations, and the sides come quickly when you sit down. One of my favorite things about this place is the Banchan they provide since it's Korean owned. The place itself is small and cozy and really never too crowded so you can get seated quickly. Great place for casual dinners as well as celebrations (love their sushi boat, it's a great deal)

對生命而言,接受才是最善待自己的方式,無論是接受一個人的出現,還是接受一個人的再也不會出現~ 滿船, 一家也開好久老店了, 韓國人的日本料理, 就是會澎湃到讓你吃不下, 但品質跟日本師傅開的就是不一樣,他家最有名的應該是大家都熟知的海膽飯, 現在是29 元一份, 朋友點了他們的sashimi 全餐, XL 的,滿桌的東西, 讓我有點嚇到, 也太多太多了吧, 如果你是只喜歡吃正宗的日本師傅做的生魚片, 這家不用來了, 但如果不是嘴巴很挑的歪嘴雞,是喜歡俗又大碗, 划算的吃法,這家是選擇之一, 我記得他們以前生意超好的, 這次去還行, 不過沒有那麼熱鬧滾滾是真的了!

The steamed dishes highlight the natural flavors of the seafood -- especially the razor clams, which were tender and delicious. The steamed buns were also a great addition, soft and flavorful. Clean, simple, and satisfying. Highly recommended!

What a unique experience!…read more Grilling, bbq-ing, etc is a norm but steaming your food on the table? Now that's something else! I really enjoyed the dinner I had, they offer lots of options, from freshly made buns, dumplings to fresh seafood. The menu is pretty extensive and they also offer cooked dishes from the kitchen. The staff are very helpful and friendly. They made sure we get the best experience as it was our first time dining at this place. We had the big eye fish as they called it and they steamed it at the other empty table because our buns and dumplings were steaming at the same time to save time. They finish the fish at the kitchen with the hot oil and sauce. We also had the pork and shrimp buns, and beef dumplings. They were delicious! You can make your sauce at the station too and they provide good options. We also got the baby oysters appetizer that was soaking in some sort of light soy sauce marinade. Also got the soft shell crab and you get 3 whole crabs for $10! It was so worth it! The whole restaurant looked clean and inviting. The booths were spacious. I would definitely come back here and try other dishes!

Food was fine, but the service needs a lot of work…read more It was our first time coming here, so I had no idea how anything worked. When we first arrived, the front was completely disorganized, and there were no lines at all. People were just crowding around the hostess table, so I had no idea how to add my name to the waitlist. There were no signs that showed where the line starts, and no line was being formed at all. The hostess kept having to walk people to their table, so it was nearly impossible to grab her attention. When I did manage to do so, she was very rude and prioritized other people before us. She obviously saw us come in before other people, but ignored that fact and just added other people to the waitlist first. Ridiculous. Their waitlist system is through Yelp, which sends you a text when your table is ready. Based on the app, it said that our table wouldn't be ready for about 1.5 hours, so we decided to walk around the outlet in the meantime. After nearly 1.5 hours, I saw that we were 2nd in line and decided to have our family walk back to the restaurant. While we were waiting outside for me to receive the text, we heard the host call my name and say that our table was ready. We met with him, and I said that it was odd since I hadn't received the text yet. He said, "Oh no, the hostess told me about you guys. You said that your phone was dead, so you'd hang around the restaurant and wait for us to call your name." No. We never said that. They have us confused with a different party. This means that if I hadn't checked the waitlist regularly and had just waited for that text, it never would've come, and we never would've gotten seated. What a messy system. Also, I've never been to a seafood boil restaurant where we have to ask for the bibs. Normally, they're given to us right when we're seated, so it was weird. We noticed other people were given bibs right when they're seated, so we're not sure why this happened. Other Kickin' Crab locations also give you an entire bottle of ketchup, whereas this place only gives small plastic cups. Weird. I think the employees and other customers would agree with me when I say that the entire place is completely disorganized because multiple orders around us were being messed up. The table to our left was missing its piece of corn and sausage in its bag of shrimp, while the table to our right was missing crawfish in their bag. The workers were obviously trying their best to straighten things out, but it didn't seem to be working. The menu is consistent with their other locations, but the market prices are a bit higher than what we're used to. Compared to the location that we always go to, this place offers bigger frozen crawfish, but the bags were mainly just the claws, so it seemed like a big ripoff. * Cajun Fries: 8/10 - nice cook, but there was only cajun seasoning on the top * Shrimp (Head-On): 9/10 - good flavor * Crawfish (Frozen): 6/10 - big crawfish, but the bag was mostly just claws and not enough garlic The place is located at the Shoppes of Chino Hills outlet, so parking is relatively easy. After being seated, the servers were nice, but it was difficult to enjoy the experience because of everything that had already happened. Overall, the service was a huge letdown, and we did not feel comfortable eating here. Places like this are why tipping is optional. The workers at the Kickin' Crab location we usually go to are way more laidback and friendlier, yet still maintain impeccable service. Would not return.
